  2. Corona discharge - Wikipedia

    en.wikipedia.org/wiki/Corona_discharge

    Corona discharges represent a significant power loss for electric utilities. Corona discharge from a spoon attached to the high voltage terminal of a Tesla coil. A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage.

  3. Electric spark - Wikipedia

    en.wikipedia.org/wiki/Electric_spark

    An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures. Michael Faraday described this phenomenon as "the beautiful flash of light attending the discharge of common ...

  4. Electric discharge in gases - Wikipedia

    en.wikipedia.org/wiki/Electric_discharge_in_gases

    Electric discharge in gases. Electric discharge in gases occurs when electric current flows through a gaseous medium due to ionization of the gas. Depending on several factors, the discharge may radiate visible light. The properties of electric discharges in gases are studied in connection with design of lighting sources and in the design of ...

  5. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect). Thermoelectric generators function like heat engines, but are less bulky and have ...

  6. Cool flame - Wikipedia

    en.wikipedia.org/wiki/Cool_flame

    A cool flame is a flame having a typical temperature of about 400 °C (752 °F). [1] In contrast to an ordinary hot flame, the reaction is not vigorous and releases little heat, light, or carbon dioxide. Cool flames are difficult to observe and are uncommon in everyday life, but they are responsible for engine knock – the undesirable, erratic ...

  7. Triboelectric effect - Wikipedia

    en.wikipedia.org/wiki/Triboelectric_effect

    Triboelectric nanogenerators are energy harvesting devices which convert mechanical energy into electricity. [ 149 ] Triboelectric noise within medical cable assemblies and lead wires is generated when the conductors, insulation, and fillers rub against each other as the cables are flexed during movement.

  8. Induction plasma - Wikipedia

    en.wikipedia.org/wiki/Induction_plasma

    Induction plasma, also called inductively coupled plasma, is a type of high temperature plasma generated by electromagnetic induction, usually coupled with argon gas. The magnetic field induces an electric current within the gas which creates the plasma. The plasma can reach temperatures up to 10,000 Kelvin. Inductive plasma technology is used ...

  9. Flash point - Wikipedia

    en.wikipedia.org/wiki/Flash_point

    The flash point is a descriptive characteristic that is used to distinguish between flammable fuels, such as petrol (also known as gasoline), and combustible fuels, such as diesel. It is also used to characterize the fire hazards of fuels. Fuels which have a flash point less than 37.8 °C (100.0 °F) are called flammable, whereas fuels having a ...
